To all whom it may concern,-

Be it known that I, CARL THEIS, a subject of the King of Prussia, Empire of Germany, residing at the city of Ohligs, in the Kingdom of Prussia, Empire of Germany, have invented certain new and useful Improvements in Devices for Supplying \Varps to Loofns, of which the following is a specification.

The object of my invention is to provide a new and useful improvement in weaving mechanism whereby pieces of unlimited length can be woven and whereby the work of warpingthat is, winding the warp-threads on a beamis avoided.

The invention consists in combining with a loom of any approved construction a holder for the warprspools and a tension device between said holder and the loom, as Will be fully described hereinafter, and pointed out in the claim.

In the accompanying drawings, Figure 1 is a longitudinal sectional elevation of a loom with my invention applied thereto. Fig. 2 is a plan view of the same.

Similar letters of reference indicate corresponding parts.

In the drawings, A is a spool-holder; B, the tension device; 0, the loom, and D the winding device.

The spools a, on which the warp-threads are wound, are mounted in several tiers-and rows on spindles on a suitable frame, and the several threads are passed from the spools over bars on which the spreading-pins I3 and c are secured, for the purpose of spreading the several threads and arranging them equidistant transversely. The warpthreads then pass into the tension device B. They pass between the guide-rollers (I, then between the tension-rollers 9, over the guide-roller e, below the tension-rollers 9, between the tensionrollers h, then over the guide-roller], below the tension-rollers h, and then to the loom, the

frame only of which is shown, as the operaton standards a of the frame of the tension.

device, said levers m carrying adjustable weights 0 on their free or swinging ends,which Weights, acting on the levers, press the upper tension-rollers downward and upon the lower tension-rollers. Between the guide-rollers d and the tension-rollers gyand the guide-roller f and the loom-frame, two bars, i, are passed between the warp-threads, which are crossed between said bars. Parallel with and at some distance from the upper tension-rollers g and h shafts p are journaled transversely on the top of the frame of the tension device and are provided at one end with crank-handles p and with arms 1). \Vhen the handles p are swung up,the arms 1) strike the bottom edges of the levers m and raise them and the weights 0 on the same and keep them raised.

I The finished cloth E passes over the roller '1" on the loom-frame, which roller is provided in placeof the beam, then passed over the take-up roller 8, which is preferably provided with pins or projections on the surface for the purpose of carrying the cloth, then over the roller t, over the roller u at the bottom of the loom-frame, then passes under the platform X, on which the weaver stands, over the guide roller '0 of the frame D, and is wound on the roller w, which is driven by a separate belt, 10. An automatic measuring device, x, is operated by friction from the outer surface of the cloth on the rollw, and is-secured on a suitable cross-bar, y, working in suitable grooves, z, of the frame D, so that as the diameter of the roll increases the measuring device can move upward. Theguide rollers (Z, 6, and f are preferably provided with circumferential grooves for guiding the threads.

The operation is as follows: The warpthreads, in passing through the tension device B, are drawn as taut as is necessary and the tension can be adjusted by adjusting the weights 0. The cloth produced in the loom is drawn from the loom under the platform X and wound on the roller w. In case a warpthread is ruptured between the guide-rollers d and the tension-rollers h, the levers m of the upper tension-roller vg are raised by swinging up the corresponding handle, p of the corresponding shaft, 12. The broken thread is tied. one end being held securely by the tension rollers h, and then the handle is swung down and the operation goes on. In case a thread is ruptured between the tension-rollers g and ICO .the loom, the levers m of the upper tensionroller h are raised and the thread tied, one end being held by the tension-rollers g. In case the warp-threads are to be drawn back from the loom-thatis, inthe direction toward the spools athis can be accomplished by the turning of the handles q of the lower tensionrollers. The operator can immediately tell when a fresh spool isto be placed on the frame A, that part of the threads which is first wound on the spools being of a different color from that of the remaining thread-that is to say, when black threads are used for the fabrics, a

' small quantity of white thread is first wound on, the spools, and then the black threads. When the black thread is unwound the white thread shows, so that the weaver knows that the spool is nearly empty and must be replaced by another.

Having this described myinventioml claim as new and desire to secure by Letters Patent- The combination, with a loom and a spool holder, of a tension device between the loom and the spool-holder, which tension device is provided with guide-rollers and pairs of tension rollers, the upper rollers of each pair of tensionrolls being mounted in vertically-movable bearings connected with Weighted levers and the lower rollers of each pair each having a handle for turningit, substantially as shown and described.

In testimony whereof I have signed my name to this specification in the presence oftwo subscribing witnesses.
